The newly developed code, named KS (Khazani-Syed) is compared mathematically with other codes which use similar techniques. In our proposal, multiple weights are used to support 'triple-play' services (audio, video and data) with different quality-of-service (QoS) requirements. The results characterizing the bit-error-rate (BER) with respect to the total number of active users show that KS offers a significantly improved performance over the previous reported techniques by accommodating additional 30 users with shorter code length and smaller code weight at BER of 10-9. In variable weight system, we have shown that KS codes with larger weight always have the best performance when other users of different weights are present in the system. 2009-07-07T08:33:08Z 2009-07-07T08:33:08Z 2009 Article Optical Fiber Technology, vol.15 (1), January 2009 pages 26-32 1068-5200 http://hdl.handle.net/123456789/6346 http://www.sciencedirect.com/science/journal/10685200 en Elsevier Inc. |
